HINTS

The HINTS line consists of a single number that determines the preferred duplex printing mode. The HINTS line can have one of the following values, which you cannot override in the Print dialog box.

Value Description
0 No preference
1 Long side duplex
2 Short side duplex

The HINTS line should be set to 0 for formats that have only a single virtual page, 2 for formats specified in LANDSCAPE mode, and 1 for all other formats.

See the example in the Header section for the correct syntax.
